Abstract

Rectal adenocarcinoma is a common cancer in the United States. Current standard of care techniques (colonoscopy and MRI) have notable drawbacks and surgeons have aggressively put most patients into surgical intervention. Developing an efficient and sensitive method to evaluate rectal cancer is urgently needed. Here we have developed a new handheld co-registered ultrasound and acoustic-resolution photoacoustic endoscope (AR-PAE) to evaluate human rectal cancer in vivo. Normal rectal ultrasound images revealed typical layered structure, while photoacoustic images resolved rich vascular supply of submucosa. Our pilot patient data suggest that AR-PAE is effective to distinguish rectal cancer from normal rectum.
